Realizing the Value of a Green Data Center

White Paper Published By: IBM

Integrate facilities and IT. Realize the value of the green data center.As data center costs continue to rise, green is the word of the day. What it means is cost savings through consolidation and lower energy usage, as this white paper shows. See the role energy consumption plays in today’s data centers, and how IBM Tivoli® solutions can help optimize energy use.

One major obstacle to efficient energy consumption, however, is the com-Highlights mon practice of separating IT and facilities information. Traditionally there One major obstacle to efficient energy has been little aggregation of facilities energy information with IT equipment consumption is the common practice of energy information. Yet facilities account for more than half of the energy separating IT and facilities information 3consumption in a typical data center. With cooling equipment requiring a large amount of electrical power and comprising a large amount of the total energy usage, any improvement in airflow management or power savings from IT equipment (for example, less heat generated) can have additional benefits 4by reducing the power required for cooling. Components such as humidifiers, UPS units and lighting also offer opportunities for energy management and optimization of the data center.
Breaking down the traditional walls between IT and facilities can provide a critical enabler for managing the green data center. With the ability to aggregate IT and facilities information, organizations can readily provide answers to the questions that enable them to move toward a green data center, including:
